SPECIFICATION forming part of Letters Patent No. 448,928, dated March 21891.

Application filed August 2,1889- Serial No. 319,595. (No model.)

' Channelers; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appcrtains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

Our invention relates to an improvement-in stone-channelin g machines;and itconsists in l certain novel features of constructionandarrangement of parts, which will befu-lly' described hereinafter.

The object of our invention is to channel rock at any desired angle fromthe truck-frame and automatically move the truck at every stroke of thechanneler. \Ve attain these objects by means of the peculiarconstruction and arrangement of the various parts of our device, whichwill be more fully pointed out and described in the specification andclaim.

Reference being had to the drawings accompanyin g this application andforming part of the same, Figure 1 is a side elevation view of ourinvention, showing side of truck with lever and drill in place. Fig. 2is an end view of same, partly in section. Fig. 3 is a'detail viewshowing. cap-piece of knuckle -joint. Fig. 4 is a longitudinal sectionalview of cappiece and knuckle.

Similar letters refer to like parts throughout the, drawings.

Referring to the drawings, A represents a truck frame or body having aflat upper surface, the same being mounted on two axles that haveflanged wheels A rigidly secured to their outer ends, said wheels beingadapted to roll on track-rails. An upright metal frame Bis secured tothe top of truck-frame A. Said frame B consists of two pieces of metala, bent to form vertical uprights on the side I) of the truck-frame A.Said pieces a are bent near their centers to form knees c andoutward-inclined extension-braces d, the ends of both pieces beiu gsecured to truck-frame A bybolts 6. Circular journal-openings f areformed at the knees c to admit the ends of trunnions g, that support thedrilling-cylinder G by means of the swivel-joint D, that is secured tothe rear side of drilling-cylinder O. The inner half of swivel-joint Dis formed of metal in ccnvexed form t' and provided with a projectin gscrew-boltj, that is adapted to pass through a central opening 7;,formed in the concave cap-piece Z, which is adapted to loosely fit overthe conveXed portion i, and the outer end of screw-bolt j is providedwith a nut m, which when screwed down binds the concaved and convexedparts closely together; but whenthe screw-nut m is loosened thedrilling-cylinder C may be revolved in a vertical plane or placed at anydesired angle in said plane, being limited in the degree of adjustmentonly by the lever 15, which is connected therewith.

The trunnions g, that form the bearings for cylinder 0 and restin. theopenings f in the knees 0, permit the drilling-cylinder O to be shiftedto an ydesired angle from avertical to a horizontal plane, so as topermit the drill n to penetrate the rock at the desired angle andchannel out a recess. The drilln isinsertedin the socket 0, which issecured to-the piston 19 in the usualmanner. \Vhen the drilling-cylinderO is supported in a vertical position by trunnions g and swivel-joint D,the drill n will stand in a line with the outside face edge oftruckframe A and will move forward or backward as the truck-frame ismoved.

. To one of the truck-wheels A on the same side as the drill nis securedrigidly a ratchetwheel y, said ratchet-wheel being secured to the outerface of said truck-wheel A and to the outer end of truck-axle r isloosely securedby nut or screw-bolt 3 one end'of the lever 13, and ashort distance outward the inner ends of pawls a are loosely held tosaid lever by means of screw -bolts o, the free ends of said pawls beingformed with inward curves 10, adapted to engage with the teeth a, formedin the periphery of ratchet-wheel y. The two pawls u are held towardeach other by the coiled spring I), that is secured byits ends to saidpawls. A vertical lever E is pivoted a short distance from its lower endto the levert between the pawls u, and bearingpins 0' are inserted insaid lever E, adapted to bear against said pawls alternately. \Vhen thetop of hand-lever E is moved toward the drill n, the top pawl u will bedisengaged from the teeth of wheel y, and the coiled spring I) will drawthe pawl it against the teeth of wheel 3 hen the lever E is turned inopposite direction, the lower pawl 10' is forced away from teeth ofwheel 3 by the bearingpin 0'. The opposite end of lever is contracted insize and formed to fit loosely in the slotted plate (1, the slot 6 beingformed of sufficient length to permit the free end f of lever t to workfreely in said slot at any angle, said slot being curved, if desired, topermit the drill to move away from the truck to work in a horizontalposition.

The slotted plate cl is provided with clipbolts g, by which it issecured to the drill n. Motion is imparted to drill a through thedrill-cylinder G, which causes the drill n to move in a vertical plane.The top of handlever E is thrown back by the operator away from thedrill, which removes the hearing-pin c from the under face of pawl u,and permits its free end to engage with the teeth on wheel y, theopposite pawl a being forced away from said wheel y by the bearing-pin 0coming in contact with the inner face of said pawl. The upward movementof drill it raises the free end of lever 25 to the limit of the upwardmovement of said lever, thereby causing the pawl 20 to impinge againstthe teeth of wheel 3 and force it outward, causing the truck A to moveslowly backward, carrying the drill n in a straight line, whereby saiddrill is caused to cut a straight channel in the rock. \Vhen the top ofleverE is forced over toward the drill 71, the bearing-pin c forces thepawl 21. away from the wheel y, and the bearing-pin c is removed frompawl 14', the tension of spring 1) drawing the free end of said pawlagainst the wheel 1 at its toothed periphery. As the drill n descends atevery stroke, the ratchet-wheel y is turned inward and the truck A movedslowly forward, thus feeding the drill forwardto out a channel. By thisconstructionI am enabled to feed the drill and truck forward andbackward at equal regular steps surely and economically, therebydispensing with extra help and broken irregular feed, time and laborbeing saved, as with the construction described the labor of two extrahands is dispensed with, as the machine when set will move in the linedirected and cut accurately with automatic feed.

This construction of feed is adapted to work on drills of otherconstruction.

Having described our invention, what we claim, and desire to secure byLetters Patent, is-- In a stone-channeling machine, a support--ing-frame, supporting wheels, a cylinder mounted thereon, a piston-rodcarrying a cut ter, a ratchet upon one of the shafts of the saidsupporting-wheels, a lever pivoted at one end upon the said shaft andits opposite end being loosely connected with the piston-rod, a pawlupon the lever for turning the ratchetwheel in one direction, a secondpawl upon the lever for turning the ratchet-wheel in the oppositedirection, and a lever which when turned in one direction disengages onepawl from the said wheel and allows the other pawl to engage it, andvice versa when turned in the opposite direction, the parts combined tooperate in substantially the manner shown and described.

In testimony whereof we afiix our signatu res in presence of twowitnesses.
